A lift engager for providing a stream of fluidized catalyst particles with an adjustable conduit and process using the lift engager. The lift engager includes a vessel with an inlet configured to receive catalyst from a reaction zone. A first conduit, within the vessel, is configured to supply lift gas into the lift engager. The first conduit includes a fixed member and a movable member secured to the fixed member and is configured to adjust a length of the first conduit within the vessel. A second conduit inside the first conduit and configured to provide fluidized catalyst to a regeneration zone.

A reforming reactor and process of using same in which residence time of feed within a chamber of a reactor is shortened. Feed is injected into the reactor into a non-reactive zone. The non-reactive zone has two portions, a first portion receiving the feed, and a second portion receiving a purge gas. The purge gas will flow from the second portion to the first portion to prevent flow of the feed from the first portion to the second portion. The combined gas may be passed to a reaction zone for catalytic reforming. The first portion and the second portion may be separated by a baffle.
